BUTTON AND BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 272,736, dated February20, 1883.

- Application filed November 13, 1882. (No model.) T

To all whom it may concern:

Be it known that l, ANNA MoKEvIT,residing at Chicago, in the county ofCook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Button Stems and Fasteners, ofwhich the following is a full description, reference being had to theaccompanying drawings, in which- Figure lisasideelevation,showingabutton and fastener embodying my inventionsecured to a piece of cloth. Fig. 2 is a vertical longitudinal sectionot'the same. Fig. 3 is a detail, being a vertical section of the nut.Fig. 4 is a detail,beingavertical section of thecollar. Fig. 5 is avertical section, showing the button with the fastening'stem, the collarand out being removed.

1 have recently applied for Letters Patent of the United States for animprovement in button stems and fasteners, and my present invention maybe regarded as an improvement in the devices therein described.

This invention is designed as an improve ment upon the inventronpatented by me January 2, 1883, No. 269,870. its object being to lessenthe cost of production and produce a strong and durable separablebutton, one in which the least number of detachable parts is employed.

The invention consists in the peculiar construction and combination ofparts constituting the separable button,the combination consisting of abutton or head, a screw-stem, arece'ssed collar, and an under button orflanged nut having a boss tor entering the recess in the collar, saidunder button or nut and its boss having a central screw-threaded openingfor connecting with the stem of the button.

In the drawings, a represents the body of a button, which may be made ofmetal or any other suitable material.

b is a stem, one end of which may be permanently secured to the body aof the button either by riveting, soldering, or any other known suitablemanner. Theother end ot'this stem b is screw-threaded, and the extremeend is pointed, so that it can be readily forced through cloth.

0 is a collar, the periphery of which is concave. One side of the collaris flat or otherwised shaped so as to fit against the inside of the bodya. In the other side of this collar is a recess, d.

e is a nut having upon one side a long flange or boss, f, which isscrew-threaded upon the inside and adapted to fit the screw-threadedstem 1). The extremity of this flangef should be tapering or pointed, asshown in the drawings, so that it can readily pass through the cloth.

9 represents a piece of cloth to which the button is secured.

The collar 0 can most conveniently be made separate from the stem anddetachable therefrom; but, if desired, it might be permanently securedto the stem.

To secure this button to a garment or other article the collar, ifdetachable from the stem, is to be first placed upon the stem. Then thatportion of the stem which projects beyond the collaris to be forcedthrough the cloth. Then the nut is to be applied, the flange of the nutpassing through the cloth, and the end of the flange passing down intothe recess d in the collar 0. I thus providefor the button-fastener anut having along screw-threaded holdingsurface without increasing thethickness of that portion which comes in contact with the cloth, andalthough the cloth may vary considerably in thickness the button will beheld firmly in place, and the inside of the nut will haveasufficientscrew-tbreaded hearing. The concave periphery of the collar 0furnishes a smooth and desirable surface for a button-hole. I do notconfine myself to the use of a stem permanently secured to the body ofthe button. The end of the stem which enters the body of the buttonmight be made screwthreaded in cases where the body of the but ton wasadapted to receive the same; but I make no claim for this construction.-It de-. sired, all of that portion of the stem which pro jects beyondthe body of the button might be screw-threaded, and the collar could bescrewthreaded upon the inside correspomlingly.

By making the flange or bossf upon the nut tapering it not only passeseasily through the cloth, but in case any thread should be carried alonginto the recess in the collar there the button or head a,a screw-stem,b,recessed collar 0, and under button or flanged nut having a boss forentering the recess in the collar, said under button or nut and its bosshaving a central screw-threaded opening for connecting with the steniot'the button, substantially as and for the purpose set forth.
